Brake pad manufacturing process and maintenance replacement
Brake pads are a very important part of the car brake system. The quality of the brake pads plays a very important role in the safety of the car. Today, the editor will talk about the production process and maintenance and replacement methods of the brake pads. I hope to help everyone. The details are as follows.
Brake pad production process introduction
1. Mixing
This is to mix the raw materials required for the manufacture of the brake pads according to a certain ratio, to break them up and stir evenly, to strictly control the mixing time and the order of adding different raw materials.
2. Steel back preparation
This refers to the spray, preheat and glue manufacturing process.
3. suppress
In this manufacturing process, the density in the mold is mainly changed to make it a qualified blank, which is mainly composed of a mold clamping process and an exhaust tool. Among them, the mold clamping process mainly focuses on the control of pressure and speed, and the low pressure and rapid processing method is adopted to make the punch and the material contact, and the material in the abrasive tool is prevented from deteriorating. The sorting process is to remove air from the mold and remove water vapor to prevent the material from hardening.
4. Subsequent processing
This process processes the shape and surface of the brake pads. It can be used to grooving, grinding, chamfering and drilling the brake pads according to the customer's requirements, and maintaining the thermal stability of the brake pads. The high-pressure electrostatic spraying method removes rust and ensures the beauty of the brake pads of the automobile.
5. Assembly
The installation of the car brake pads is the assembly of the alarm, and it is important to check the compression ratio and density of the brake pads.
6. Packaging
This is the last process, mainly to package, print, and store the brake pads production date and batch.
Brake pad maintenance replacement
1. When the brake pads are contaminated with oil, they need to be replaced.
2. Replace the brake pads and replace the left and right wheels at the same time.
3. Whenever possible, use the same material as the old brake pad. The replacement material is one level higher than the old brake pad material.
4. The thickness of the friction material on the disc brake pad should not be less than 2 mm, and the thickness of the friction material on the drum brake pad should not be less than 1.5 mm.
5. Vehicles with warning lights installed. When the thickness of the friction material is less than 3.5 mm, the light will be on. Usually, two brake pads are replaced, that is, the brake disc should be replaced.
6. Try not to replace the asbestos material with a non-asbestos material instead of a semi-metallic material.
The above is about the brake pad manufacturing process and maintenance replacement matters, I hope everyone knows the brake pad production process and maintenance replacement matters, it is helpful to everyone.
